Filed Feb. 21, 1967, Ser. No. 617,535 3 Claims. (Cl. 57-120) ABSTRACT OF THE DISCLOSURE The invention comprises the securing of a spinning ring in fixed and leakproof relation to a supporting member or mechanism so as to avoid any connection between these two parts through which oil or lubricant may leak, so that when the ring wears out, it and the supporting member are removed as a unit and replaced by a similar unit.

Background of the invention The invention relates to the field of spinning and twisting yarns. Prior devices of this kind generally had leaks between the spinning ring and its supporting member and oil passing between the ring and the supporting member allowed some rings to receive less lubricant than others on the traveller bearing surfaces resulting in unequal tensions of the yarns being spun or twisted. Also leakage of oil caused contaminated yarn which was being spun or twisted and lubricant on parts of the spinning frame where it was not desired.

Brief description of the drawings FIG. 1 is a top plan view of a spinning ring mounted on a supporting member and provided with means for supplying lubricant under pressure to the spinning ring.

FIG. 2 is a fragmentary, sectional elevation thereof on an enlarged scale on line 22, FIG. 1.

FIG. 3 is a sectional elevation similar to FIG. 2 applied to a spinning ring of different construction.

FIG. 4 is a fragmentary, top plan view of a spinning ring and supporting member of another modified form.

FIG. 5 is an elevation thereof.

FIG. 6 is a sectional elevation thereof on an enlarged scale on line 6-6, FIG. 4.

FIG. 7 is a fragmentary top plan view of another modified construction of spinning ring and supporting member.

FIG. 8 is a side elevation thereof.

FIG. 9 is a sectional elevation thereof on line 9--9, FIG. 7.

The drawings show in FIG. 1 a spinning ring 10 having an inner ring 11 and a traveller 12 of usual construction which spins in contact with the ring. The ring is lubricated by oil or other lubricant passing into a passage 15 leading to a circular reservoir 16 arranged in the ring between the body portion thereof and the ring 11. The inner ring has passages of any suitable type formed between it and the main ring through which passages lubricant can pass to the surfaces of the ring which are contacted by the traveller.

Oil or other lubricant is supplied automatically to the spinning ring from a supporting member 20 which has a threaded connection 22 to which a suitable coupling 23 may be removably secured, the coupling forming a part of the automatic mechanism which supplies lubricant to the spinning ring. Devices forsupplying lubricant in this manner are well known and further description of the same is therefore not believed to be necessary.

This ring is supported on the supporting member 20 by means of a shoulder 18 on the ring which rests on the ice inner edge of the annular Web 24 of the supporting mem- At a part of the web or body portion 24 of the supporting member a passage 25 is provided extending from the outer edge to the inner edge of this member. The ring has an inlet opening 27 which terminates in the outer edge of the ring and connects with the passage 15 and the reservoir 16. The ring is so positioned in the supporting member that the passage 25 registers with the passage 27. A tube 26 is provided which connects these two passages, this tube being so formed that after being passed through the passage 25 of the supporting member, its inner end is forced into the passage 27 of the ring to form a drive fit.

To form a liquid-tight connection between the ring and its supporting member, the tube 26 is provided at its other end with an enlargement 30 which fits against an annular shoulder 32 formed within the passage 25 of the supporting member. When the ring is seated within the supporting member, the tube 26 is driven toward the ring so that the enlargement 30 is driven into a drive fit contact with the shouldered part 32 of the supporting member, thus forming a fluid-tight joint between the ring and its supporting member and also a strong mechanical connection between these two parts.

A further assurance against seepage of lubricant in the connection between the supporting member and the spinning ring is preferably effected by means of a sealant 40 which extends about the outer surface of the tube 26 so that the inner surface of the joint between the ring and the supporting member is securely closed by means of such sealant, so that no oil or other lubricant can escape or seep through the junction between the ring and the supporting member.

In order to further make very certain that no leakage will take place between the supporting member 20 and the ring after they have been mechanically secured together, we may provide between the adjacent parts of the ring and the supporting member a sealant of any suitable kind which will penetrate into any small crevices or openings through which oil may pass and bond the parts contacted thereby to each other. For example, the inner edge 36 of the supporting member which contacts with the spinning ring may be provided with a sealant indicated by a heavy line at the contacting surfaces of the supporting member and the ring, as indicated at 38.

By providing a drive fit between the ends of the tube 26 and the ring and supporting member, a secure mechanical joint is provided which may however not be tight enough to prevent seepage of lubricant through this joint and therefore a sealant is employed to prevent even a possibility of leak at these drive fit joints. The fact that the drive fit produces a strong mechanical joint also augments the joint produced by the sealant, in that relative motion between the tube 26 and the ring or supporting member which might break the seal produced by the sealant is prevented.

In FIG. 3 we have shown our improvements applied to a different type of spinning ring which is of somewhat elongated elliptical shape in vertical cross section, and which has an oil passage 50 extending approximately radially through the same to the bearing surface of the ring. This ring also has an outwardly extending shoulder 52 which is adapted to seat in an annular groove 54 formed in the web 56 of the supporting member. The supporting member is provided at a part thereof with a passage 58 extending through the same from a threaded aperture 60 for receiving a suitable coupling leading to the oil passage 50 of the spinning ring, and we provide a tube 62 in the passage to the supporting member. This tube is similar to the tube 26 shown in FIG. 2, one end of this tube extending into the hole in the spinning ring and held there- (e) the portion of the fluid passage within the spinning ring supporting portion adjacent the lubricant receiving opening being an elongated passageway the same diameter as that of the spinning ring lubricant receiving opening,

(f) an internal slightly enlarged cavity in said fluid passage which is disposed immediately adjacent to the interior end of said elongated passageway, and which has an inwardly tapering shoulder section immediately adjacent the interior end of said elongated passageway,

(g) an elongated tube of greater length than and disposed within said elongated passageway, said elongated tube extending into said lubricant receiving inlet opening of said spinning ring, and being in tight firictional engagement with both said elongated passageway and said lubricant receiving inlet opening,

(h) the interior portion of said tube having an integral enlarged annular section which engages the interior of said slightly enlarged cavity, and has a contour which matches and is in tight sealing engagement with said tapering shoulder of said enlarged interior cavity, whereby a sealed leakproof conduit is provided through said spinning ring support and fluid coupling member and said spinning ring.

2. The spinning ring assembly as set forth in claim 1,

wherein:

(a) sealing compound is disposed between the outer surface of said elongated tube and the adjacent surfaces of the elongated passageway and the lubricant receiving opening of the spinning ring.

3. The spinning ring assembly as set forth in claim 1,

wherein:

(a) said spinning ring support and fluid coupling member includes a junction block through which said fluid passage extends, and which has an outer surface which contains said enlarged coupling receiving opening.
